There are a few other features that brctl offers, but they are beyond the scope of this page. In order to get a better understanding of them, you should read the brctl Manual Page.

The documentation that i suggested recommends "brctl show <brname>" but in DD-WRT the proper syntax is "brctl showbr <brname>". If you have any doubts, simply type "brctl" and a list of available commands will be displayed.
